Batteries
Pick the batteries. Your agent gets the manual with them.
26 batteries across 12 categories. Every one ships path-scoped rules, at least one skill and five solution docs. No config, no battery.
A battery is more than a package and an env var. It is what an agent has to know before it touches that part of your repo: where the code lives, what it must never do there, and the failure modes someone already hit.
